Interactive Book in interactive book
in the learningsapps.org-tools is a tool named matrix wihich allowed to put moduls under one modul. it is possible to put a matrix in a matrix. This option I miss a little in h5p (but only a little because h5p is much better than learningapps).
In the interactive book-modul it is possible to put a course presentation-modul. So it is possible to put many course presentation-modul in one interactive book. But you can't put an interactive book in the course presentation-modul and you also can't pit an interactive book in an interactive book. So you can't build a interactive learn modul in a was like the Russian Matrjoschka Puppet.
If sometime it can be build with the h5p-tools especially the interactive book-modul in that way there will be great results of interactive courses.
But, I wrote it, it is only a dream...
Thnx for reading,
